Lowering Alarm; Emergency Lowering Knob; Guardrails; Lanyard Anchors - Snorkel TM12 Series Operator's Manual

Chapter 4 – Safety Devices
If the chassis is tilted more than two degrees side-to-side
or front-to-rear, the drive and lift functions will not operate
and an alarm will sound.
Lower the platform and drive to a level surface when the
drive/lift level sensor alarm sounds.
The drive/lift level sensor system is for added protection
and does not justify operating on anything other than firm,
flat, level surfaces.

Lowering Alarm

As the platform is lowering, the alarm emits a loud beeping
sound to warn personnel in the work area to stand clear.
Danger
Pinch points exist on the machine. Death or serious
injury will result if the platform lowers onto personnel.
Stand clear while raising and lowering the platform.
Be careful when lowering the platform. Keep hands and
fingers away from the machine components.

Emergency Lowering Knob

The emergency lowering knob may be used to lower
the platform if there is a malfunction in the hydraulic or
electrical system. The knob is mounted at the front of the
aerial platform (refer to Figure 4.4).

Guardrails

The guardrails (refer to Figure 4.5) help protect personnel
from falling off the platform.
The guardrail system includes:
• A top rail
• A mid rail
• An entry chain
• Toeboards around the sides of the platform.

The entry chain allows for access to the platform. After
entering the platform the chain must be securely fastened
before operating the machine.

Lanyard Anchors

Figure 4.5 – Platform
Lanyard Anchors
Two lanyard anchors for fall restraint anchorage are pro-
vided below the upper controls at the front of the platform
(refer to Figure 4.5).
Note
The lanyard anchors are not for lifting or tying the ma-
chine down.
• All personnel in the platform must connect their fall
restraint device to a lanyard anchor before raising
the platform.
• Attach only one fall restraint device to each lanyard
anchor.
• Do not use the aerial platform for personal fall arrest
anchorage.

Tilt Alarm

If the aerial platform chassis is out of level more than two
degrees side-to-side or front-to-rear when the platform is
raised, an alarm will sound.
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not drive or position the aerial platform for
elevated use near any drop-off, hole, slope, soft or
uneven ground, or other tip-over hazard.
Completely lower the platform and then drive to a level
surface when the tilt alarm sounds.
The tilt alarm is for added protection and does not justify op-
erating on anything other than firm, flat, level surfaces.
